Claims.

This invention relates to novel and useful improvements in devices for use in association with farm equipment.

An object of this invention is to unload wagons of its contents, particularly ensilage or other forage, to reduce the amount of manual labor involved.

Another object of this invention is to unload a wagon by improved means, the said means including an arrangement for increased mechanical advantage in moving a battle or gate longitudinally of a wagon, thereby urging the contents of the wagon therefrom.

Another object of this invention is to provide a simplified device for unloading wagons which is inexpensive and which is smoothly operative.

Ancillary objects and features of novelty will become apparent to those skilled in the art, in following the description of the preferred forms of the present invention, illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of one form of the invention;

Figure 2 is a longitudinal sectional view taken substantially on the line 2--2 of Figure 1 and in the direction of the arrows, portions being shown in elevation;

Figure 9 is a longitudinal sectional view of another form of the invention;

Figure 10 is a longitudinal sectional view taken substantially on the line lll---HJ- of Figure 9 and in the direction of the arrows;

Figure 1'1 is a transverse sectional view taken substantially on the line |l--H of Figure 9 and in the direction of the arrows, and;

Figure 12 is a sectional detail of construction taken on the line l2l2 of Figure 9.

Referring now to the first form of the invention a conventional wagon is illustrated having a bottom 50, sides ['2 and I4 respectively and a back l6. Opposed pairs of rails generally indicated at 20 and 22 respectively are supplied on: said sides l2 and [4' in order to slidably receive a gate 24 therein. The said back [6 in this form of the invention is supplied with an aperture 26 in order to accommodate the travel of the resilient roller 28. This roller is journaled on a suitable bracket 30 which is in turn secured to a bafile 32.

The said baflle may be made in varying widths and heights in order to accommodate the size of wagon on which it is attached. Also secured to the said baffle is a plurality of braces 34, 36, 38 and 40 respectively which are utilized for the purpose of supplying rigidity to a tube 42 and a housing 44. The said housing is detachably secured to the said baffle 32 through the medium of a wing nut and bolt construction generally indicated at 46, which attaches to a suitable angle bracket 48 and a base plate 50. Of course, suitable, conventional bolts may be used wherever it is found desirable and when it is found expedient to otherwise secure elements together such as by' welding, this expedient may be resorted to; The said baffle 32 may be made of metal or wood in accordance with the prerogative of the manufacture and strengthening members may be supplied in accordance with the dictates of sound engineering principles.

The said tube 42 has a flexible element 52 extending therethrough, the flexible element being either a rope, cable or the like. One end of the said flexible element has a suitable ring 54 attached thereto. The cable or rope extends through the tube 42 and is entrained about a pulley 56. This pulley is journaled in the said housing 44 and an opening is provided at the lower portion thereof in order to permit the cable or rope to extend therethrough. Then the'flexible element terminates in a loop 58 which is secured to a suitable anchor such as the eye bolt 66. This eye bolt may attach to one of the cross members of the wagon which is appurtenant thereto.

At the forward end of the said tube 42 there is: supplied a guard 62 which is also utilized for the purpose of a hand grip for use in manipulation of the device.

It is now readily apparent that by pulling the ring 5Q the force is transmitted directly to the baffle 32' thereby urging whatever product is in the wagon therefrom.

Referring to Figure 3 the preferred use of the invention is illustrated. Here a conventional tractor 66 is shown having a chain 68 attached 3 to the drawbar thereof and to the said ring 54. The wagon is in turn anchored to a suitable element through the medium of the tongue I0.

Referring now to Figures 6-8 a second form of the invention is illustrated. Here the conventional wagon is indicated and the differentiating features may be seen in the roller construction. Here a bafile 80 is illustrated with the housing 82 secured on the opposite side thereof. An aperture is formed in the said baffle 80 for reception of the tube 82. Braces 84 and 86 respectively are attached to supports 88 and 90 of the said baffle 80 and also to the said housing 82. An aperture 92 is formed in the lower portion of the said baflle 80 in order to accommodate the passage of the flexible element 94. This flexible element is attached to an eye bolt 96 as is the first form of the invention. It is noted that a pair of rollers 98 and I00 respectively are utilized in this form of the invention, being attached to bearing members or depending brackets I02 and I04 respectively. These bearing members I02 and I04 respectively are attached to the brackets 84 and 86. The operation of this form of the invention is identical to the operation of the first form.

Referring now to Figures 9l2 another form of the invention is illustrated. Here a conventional wagon is shown as a recipient of the invention and the baffle I I0 is formed with upper and lower spaced apertures H2 and H4 respectively. A pair of pulleys or sheaves IIB and H8 respectively are journaled in a suitable bracket I20 for accommodation of a flexible element I24. The roller construction in this form of the invention is identical to that roller construction of the second form.

The said flexible element I24 is secured to a pulley housing I26. The said pulley housing I26 is also secured to a bracket I28 which is in turn rigidly attached to the under surface of the said wagon. The said flexible element I24 extends through the lower aperture II4 and is entrained over one of the pulleys. Then, the flexible element returns to the pulley within the pulley housing I26, thence is entrained through the lower aperture against and over the other pulley of the said pair of pulleys. Then, the said flexible element I24 extends through an aperture formed in the endgate I30.

A shield I32 which is substantially triangular in cross section is secured to the said baffle I I0 and has a stiffening member I34 extending longitudinally thereof, situated in the apex of the substantially triangular member I32. A hook I36 depends from the stiffening member I34 and has the flexible element I24 entrained therethrough.

The lower portions or legs of the substantially triangular shield I32 are rolled as at I40 and I42 respectively for reducing friction when sliding the shield in removal of the contents of the wagon therefrom. Handles I46 and I48 respectively are attached to the said shield I32 for assistance in actuation of the device.

When ensilage or forage is trapped and blown by the conventional field cutters into a wagon box equipped with the present invention, the wagon is then driven into position at a forage blower. The brakes on the tractor pulling the ensilage or forage wagon are set and then the endgate at the rear of the wagon is opened and the said chain 68 is secured. The tractor pulls the bafiie at the desired speed for unloading into a hopper or conveyor I60 to be blown into a silo or other place for proper storage.

By utility of the present invention many man hours may be saved thereby rendering the use of the present invention economical. Also, the hazards connected with manual unloading of the ensilage are dispensed with and the rate of speed of unloading may be regulated in accordance with the prerogative of the user of the invention.

While there has been described and illustrated but preferred forms of the invention, it is apparent that variations may be made without departing from the spirit thereof. Accordingly, limitation is sought only in accordance with the scope of the following claims.
